Install 3.71 M33 on Your PSP in 4 Easy Steps
This post may be a bit late but I know a lot of you PSP owners out there are looking for installation guide for the 3.71 M33. For a bit of information, 3.71 M33 was created by Dark Alex. In other words, M33 is Dark Alex. Now on to the instructional guide!
Requirements
- You must have 3.52 M33-4 installed on your PSP. If you don’t have one yet, lucky for you I wrote a guide on installing 3.52 M33-4 too.
- A Slim (PSP2000) or Fat PSP (The older version) with 78% or more battery.
- PSP AC adaptor
- A USB Cable
- A Computer
- Ability to understand and follow instructions
- If you have the fat PSP, configure GAME folder to run on 3.52. How? Shutdown your PSP. Then power on your PSP while holding down your R button. This will take you to the recovery menu. Go to Configuration > Game folder homebrew and check if 3.52 is enabled. Press X or circle if not. Exit the recovery menu.
That’s it. if you have all these then you are ready to go!
Now here are the 4 very easy steps:
- Download the 3.71 M33 installer pack I’ve made just for you. Extract the file to anywhere on your computer.
- Connect your PSP to your computer via USB and copy the UPDATE folder to ms0:/PSP/GAME
- Go to your XMB menu and run the M33 update program. The screen will go black and this is normal. Follow the instructions. Be sure you have your PSP plugged-in to the AC adaptor. Screen will change to the Sony Update screen. Accept and update.
- This last instruction is VERY important. After the update is finished, the updater will ask you to reboot by pressing X or O. Do so, press X or O and the PSP will restart. Have fun on your new upgraded PSP!
After successfully upgrading your PSP to 3.71 M33, you can install the 3.71 M33-2 update by following the guide I made here. Special credits go to Dark Alex. You can send him donations on his website via PayPal.
Rush to at home training for cissp certification , a Microsoft mcts certification or a significant ase certification.
UPDATE: I wrote a guide on how to add the 1.50 Kernel Add-on for 3.71 M33. Please check it out if you need it.

Please read step 2.
Hey thanks alot … you are life saver … I am total noob in upgrading the psp firmware. I was using 3.52 M33 – 3 and I am using 3.71 M33 !!!! Thanks to you
Keep up the good work
If you don’t mind my asking, what’s 3.71 got that 3.52 hasn’t? I have the m33-4 already; tell me why I should update… thanks
3.71 M33 supports the latest games and it has a theme changer on the XMB menu. You can also view the photos while listening to music simultaneously. The video has also added options like search by time interval.
It still supports backup ISO games and of course you could still play and execute homebrew using Noobz eloader.
Thanks.

Hey guys theres a new 3.71 M33-2. This is the latest custom firmware.
Ok, I just did the 3.52 m33-4 update, and when I go to use this one it sais “This program requires 3.52 m33-3 or higher.”
What did I do wrong? System information sais I’m at 3.52 m33-4.
Scratch that last comment, I skipped right to the steps of doing it. Didn’t do this part.
“If you have the fat PSP, configure GAME folder to run on 3.52. How? Shutdown your PSP. Then turn on your PSP again while holding your R button down. This will take you to the M33 recovery menu. Go to Configuration > Game folder homebrew and check if 3.52 is enabled. Press X or circle if not. Exit the recovery menu.”

Try placing a UMD on your PSP drive. If it doesn’t work press Select button while on the XMB menu to bring out the VSH menu. Try changeing the UMD ISO settings.

@Kappukappu: Have you tried placing it on the ISO folder on the root of your memory stick?
Try going to the recovery menu and changing the GAME folder kernel to 3.71. If you have plugins enabled, try to disable them first.
I never experienced that problem before.
Here are the settings on my VSH menu that works:
CPU CLOCK XMB: 333/166
CPU CLOCK GAME: 333/166
UMD ISO MODE: Normal
ISO VIDEO MOUNT: NONE

“error 0×00000060 checking idstorage degeneration.
Help me pls
Ok, I have ran the 3.71 M33 updater many times (checking and double checking that my kernel is set to 3.52) and I still get the error that a couple other people got: “this program requires 3.52 m33-3 or higher”. I am completely lost as to how this is happening. I have to say that I am a Homebrew first timer, just got my self a Pandora’s battery kit and downgraded from 3.71 ofw. Then I upgraded from 1.5 to 3.52 M33-4 (thanks to the handy guide on here) and am now attempting the 3.71 M33 update. PLEASE help me! Than you!!
Josh…i had face the same problem with u too….can anybody help us? tq
Try this:
Connect PSP to PC then go in to recovery mode, advanced, toggle flash1, then delete the config.se file.
Josh i have try this but i still can’t upgrade…maybe u can give a try i got this help from psphack
i’ve upgraded to m33 3.52-4, and trying to upgrade to m33 3.71, but it keeps on bricking. it seems like the instructions are pretty clear, i have a FAT psp, @ M33 3.52-4, GAME folder running at 3.52, copied the UPDATE folder to PSP/GAME. ran it and it gives me an error at 99%, and this has already happened three times.
i figured if i can follow the much harder instructions to unbrick my PSP, i can do this, what’s happening? help! thanks.
Need help guys many iso and cso wont work .i try every setting in recovry and xmb.anyone face same problem in 3.71m33?
hai guys i had been searching the solution whole day but i think i give up now ….
i’ll stay at 3.54-4 M33….
Hi guys,
mine can only read cso but not isos!! OMG has anyone found a solution??
guys i found something tt works!!
Make sure the title of the ISO/CSO is short.
Example:
Correct — Fifa07.iso
Not Correct — FIFA-07-[PSP][EUR][www.torrent site.com].iso
——————————————————————-
Now right click on the ISO/CSO file and choose Properties. Make sure the Read Only and Hidden box is unchecked and the Archive Box is checked.
——————————————————————-
Go into recovery mode (Hold R shoulder button down while turning on PSP)
Now go to configuration then to UMD MODE and keep pressing X till you see Sony NP9660 NO UMD.
When it is set to the above setting go to BACK and press X.
Now go to ADVANCED and press X.
Go to ADVANCED CONFIGURATION and press X.
Make sure all the settings here are disabled.
Now EXIT out of recovery.
Now try the ISO/CSO.
I am just going to try to re-downgrade with the pandora battery and then start over. if it works then maybe it was just a bad install?? the only thing i did between the two upgrades from 3.52 M33-4 to 3.71 M33 pop in a memory stick that had game iso’s on it just to see if they ran, and they didn’t. so then i continued on to to the 3.71 M33 update. I will post if I get it completed.
looks like i was so excited to get 3.52 M33-4 on my ofw PSP that i skipped a couple of steps at the end of the update. If others are having this problem just follow the last steps all the way through before you jump for joy! I now have a 3.71 M33 PSP. I sure do love pandoras battery. Thanks again for the perfect guides!
Sebas i try as you said.but nothing work.GUYS JUST STAY WITH 3.52m33-4.ITS BUG FREE..STABLE.. AND BEST .WAIT FOR 3.71M33 TILL SOME TIME..OTHERWISE YOU FACE MANY PROBLEAMS MAYBE!

wow…..i finally make it to 3.71 m33-2

Hello all, I am getting ready to go to Iraq and I just purchased a PsP to keep my sanity, I have had it just long enough to figure out how to load music and pics on it and how to update the system, it is currently sitting at 3.72 sony update, but in my adventures i discovered ou can download games in .cso and iso format, but I can not figure out what to do from there, and I am still reading, I know the answer prolly pretty simple but I could really use some high speed expert advice on how to tweak this and make it to where I can down load my games and movies so I don’t have to ruin umds with all the sand and stuff and keep my sanity please.
Sincerly Mutt
Iraqbound…mayb u shud try reformatting ur memory stick usingur psp ferst…i hope it help…

Hi carlo. Use Winrar or winzip. Find it on google.
Just wanted to let you know that when I tried to download your 3.71 M33 Installer pack, it said that the files were gone so could you please update that? I’m in the current process of updating to 3.52. Thanks and great site man
Invalid Quickkey. This error has been forwarded to MediaFire’s development team.

nice guide man, i am going to try it but the download for the 3.71 M33 installer pack says “Invalid Quickkey. This error has been forwarded to MediaFire’s development team.”
I heard the normal 3.71M33 was buggy and stuff, try upgrading it to 3.71M33-2 it should work. Where is the 1.50v2 kernal addon? is it in the installation?
Thanks man for the great guide. Much Appreciated
There you go. I’ve updated the 3.71 installer pack already. It doesn’t include the 1.50 kernel but i’ll write another guide about it in the coming next few days.
Thanks all!

Do I also need to install 3.52 M33-4 on my new slim before able to upgrade to 3.71 M33?
I just bought the original slim set recently.
Do I follow the steps accordingly? From 3.52 M33-4 to 3.71 M33 then to 3.71 M33-2. Or can I install 3.71 M33-2 straight.
If ever one day, I decided to remove the firmware upgrade, is it possible to roll back to the original firmware when I bought it?
Please help. Thanks.
Sorry to dual post, will this steps worked on a PSP2006?
i can’t seem to download the installer pack…
my psp is version 3.10. how do i upgrade it to 3.71?
No iso or csos work on 371m33-2 wat do i do
i follow the step to upgrade my psp to 3.71 but it says game cant b started. y?
@Jumi, you say you have 3.10 firmware. You can’t upgrade to 3.71 M33. You have to downgrade to 1.5 first. Be careful with tinkering your PSPs because I won’t be held responsible if something happens to your device.
@Anup: Make sure your isos are named properly. The filenames should not exceed 50 characters. Or try resetting your device.
idol can you please update the download site for 7.31 M33, can’t download it. thanks in advance.
Thanks a lot!!
hi all 3.52m33-4 is good.any one have?
hi stylemo how are you man..just keep going
when i try to load the update it says this update requires 3.52 m33-3 or higher and im already 3.52 m33-4
@kappukappu: I’m doing great man. I’ve got lots of work to do man
@JAYJAY402: Try to reset your device or format your memory stick. Haven’t encountered that one yet.

Hey dude, i think your installer pack for 3.71m33 is still down… please have time to upload it… thanks man!
i have fat psp i have done 3.71 now its not playing games from memory card and tell me haow to downgrade it
hi tell me haow can i play games in my psp its fw is 3.71 original
@babu – you can actually play games from your memory card. you can play PSP demo games if you want. or you can just buy UMDs for your PSP. If you meant playing backup games, you should first downgrade that PSP using Pandora’s battery or let someone with xperience downgrade it for you.
Unable to upgrade from 3.51M33-1
Grateful for some help/advice/links for the problem I seem to have…
Have been using Devhook to give me firmware 3.11, but needed to upgrade further so used M33Creator to get to 3.51M33-1. However I now need to upgrade further and want to go to 3.71.
This is where my problem begins. I have downloaded the correct software and boot files and followed the instructions exactly (just like I did to get to 3.51) for 3.52M33 (as I undertsand to get to 3.71 I require to be at 3.52M33-3 (or 4)) however when I run the M33Creator I get the following error “3.52 PSAR size doesn’t matchâ€. Have tried different versions of 3.52creator and 3.52 BOOT. Have also formatted MS (1GB) and used another MS (1GB) which still did not resolve the problem.
What I would like to know is :-
a) how can I upgrade to 3.71 – what am I doing wrong ?
b) If somehow I can’t upgrade further because of a problem, how can I return to 1.50 so that I can then upgrade to 3.71 – hopefully with instructions.
c) Are there any other options that I could do without “bricking” my PSP ?
Thanks in advance for any help provided, and keep up the great work.
@jtj43: If you have 3.51 M33-1, I think you may have to install the updates first. I mean update it to 3.51 m33-7.
After that, you can now install 3.52 M33 following my guide.
And If somehow that doesn’t work, you can get return to 1.50 by using the recovery mmode. You can get to it by shutting down your PSP and restarting it while holding the R button.
Hi.. cant download the file coz the link is broken.

hi stylemo great work.and thanks.any recovery or downgrader to 1.5.if somthing gose wrong…
@kappu: thanks. you gave me an idea. I’ll write a post on how to get back to 1.5 firmware.
my psp is bricked. i cant see any difference between the screen when i turn it on and when its switched off. is it semibricked or..? and how do i unbrick it? help>
and ive tried the backlight button many times…
before it got bricked thr was this message:
some of your idstorage keys have not the correct values, probably due to a downgrader. In order to continue, press X to restore the correct values, press R to exit.
i pressed X, and it got bricked.
Tinkering with your PSP is a very delicate process man and you should know that. Stylemo wrote a very good and easy to follow guide so guys who are new to all the hacking thing can easily do the process.
Hey maybe you should try the recovery mode. Turn off your PSP. Be sure that the green power light is off. Then turn it on while pressing the R button. If you are successful you can recover it.
The cause of most of these problems are faulty memory sticks. You guys should know that. Format your Memory Stick before doing the process to be sure.
how do u know if your memory stick is corrupted?
do i need to have the memory card formated with only this update on the memory stick?
reason why. it just reboots and plays my umd game disk when trying to do the update.
thanks for any nfo to cure my problem.
Hi, I cant start my recovery menu, nothing happens when I press R when starting the psp. Could the psp brick if I dont have the right “kernel” set?
hi i think my psp is bricked…i tried a xmb then my psp juz hang up…what shud i do…all i can open is the recovery menu….i have a 3.71 fw
hi i think my psp is bricked…i tried to
put a theme then my psp juz hang up…what shud i do…all i can open is the recovery menu….i have a 3.71 fw
i have already started the program and the screen turned black as mentioned but it stays black like forever?
@Jurvis: You sure you followed the instructions step by step?
yes. very slowly trying to set everything!
i faced this problem like boom:some of your idstorage keys have not the correct values, probably due to a downgrader. In order to continue, press X to restore the correct values, press R to exit.i was scared to press X coz i dont want my PSP to get bricked what do i do now?
@Jurvis: It’s your choice dude. Press X or exit the installation. It’s like choosing between the red pill and the blue pill and finding out how deep the rabbit hole goes. Well, it’s up to you. It’s your own risk dude.
I’m a risk taker so if you ask me, go ahead and press X.
hey thks it worked!

Now go to ADVANCED and press X.
Go to ADVANCED CONFIGURATION and press X.

Now EXIT out of recovery.

- can you set it up so it does not require a UMD to play.
Thanks
dude you are the man thnx for the guide made mine work like a charm
@secretto:
I sure could. Why don’t you try resetting your device?
Yes. That’s what the VSH menu is for. You can enable/disable it via the recovery menu.
Thanks all.

hi there ,could you please tell me which,psp would be the best to buy for my son for xmas, the lite or the old model, as i am very interested in the 3.71 m33-2 mod.any help and advese would be greatfully received, many thanks richard, new zealand
@richard amos: If you ask me I’d stick to the PSP Phat. What I love about the Phat is the IR Port that can be very useful if you know how to use it.
The PSP Lite however is cool too. It has a TV out which means you could connect it to your TV and it’s much lighter. But it has no IR Port.
Both PSPs are hackable and downgradable. You can also run 1.50 kernel based application on these two but if you really want my opinion I’d stay go for the Phat.
Hey thanks! omfg your the best, great guide and everything else. keep up the good work
If you get the error: “This update requires 3.52 m33-3 or higher” and you’re on 3.52 m33-3 or m33-4, then you need to change the homebrew kernel mode to 3.52 in the recovery menu.
Hey my freaking psp just bricked on me, and the recovery thing for 3.71m33-3 isnt working… what should i do?
@dark shogun: hey what did you last do before you bricked your PSP? If you can’t access the recovery menu then you need pandora’s battery.
i was trying to figure out how to fix the problem i had with the game menu, it wouldnt allow me to access the game i downloaded. and i can access the m33 recovery menu.
i was trying to figure out how to fix the problem i had with the game menu, it wouldn’t allow me to access the game i downloaded. and i can access the m33 recovery menu.
when i try running the recovery file it says:
“verifying 371.PBP… OK”
“verifying umodule.prx…OK”
“Press X to start the update, R to exit”
(i pressed x)
“Starting sce updater, Wait…”
My psp says its at 3.52 m33-4 but when i try to install 3.71 it says it needs 3.52 m33-3 or higher does anyone has a solution
i already solved it sorry! i had in recovery mode 1.50 kernal selected instead of 3.52 sorry
This is probably a often asked / dumb question, but if you swap out your memory card with another one will it mess anything up, or get rid of 3.71 M33?
@jkillah1: That question was first asked by you. Swapping memory cards won’t affect the firmware. once you had the firmware installed, it stays on the device and not on the memory stick.
PLEASE TEACH ME HOW TO DOWNGRATE MY PSP VERSION 3.73 THANKS I’LL WAIT FOR REPLY ^_^
will it get bricked if you try it with a 3.71 offciial firmware
cos please tell me
please

@kannuto: thanks dude! let’s go get some beer some time in the future.
Congrats! Your link is the first google shows for “3.71 installer”
stylemo..tnx for this instruction!
Sure master stylemo just text me…:D
dude,i followed all ur tutorials, my psp was successfully upgraded from3.51-3.71m33-3, thank you for that, i really appreciate ur site.but now my problem is everytime I use the internet browser,it says internal error occured,why is dat? wat should i do?
@wacko! : try resetting your device dude. Go to settings > system settings > restore default settings. That will fix your error. That occured to my PSP too and that’s what I did.
Help! I have 3.52 M33-4 on my psp and I’m trying to upgrade to 3.72. I downloaded the file and copied the UPGRADE to my GAME file. However, when I select the update file in my XMb file, the screen turns black for a moment (as it should), but then a message pops up saying “The game could not be started. (80020148)”. I have a UMD disk in it and everything.When I try pressing select in the XMb menu to configure it, nothing happens! Please help.
@jake_01 : That’s a common problem. I assume you haven’t read the requirements part well. You really don’t need a UMD in the drive too. All you have to do is configure your GAME folder to run on 3.52. How? Read the post above again.
Alright, I went to my recovery menu, changed the game folder hombrew to 3.52, went back to my game folder to try the update again, and the same thing happens! What am I doing wrong?
Hmm I followed your instructions, but when i run the upgrade file I get a message saying that my psp requires a firmware of 3.52 m33 or higher to upgrade. However, I am 100% positive that my psp is running on 3.52m33 firmware. I also changed the game folder homebrew to 3.52 kernel. Anyone know what’s wrong?
@hing
You’re not using 3.71 m33? Then that’s the problem.
Oops wrong place D=
No it’s ok I was silly. I didn’t properly read the text which stated it requires 3.52 m33-3, the -3 being the important part. After updating to 3.52m33-3, everything worked fine.
Hey stylemo
THX for the guide and everything, but i tried to upgrade to 3.71 M33 using ur guide. i had 3.52 M33-4 and all the requirements i needed, i upgraded successfully, but after i restart my psp in step 4, i cant move though the icons (IN THE XMB MENU). i cant press any button or do anything. so i downgraded to 1.50 AGAIN and i tried the same process AGAIN, 1.50 –> 3.52 M33-4 –> 3.71 M33
and still have the same problem.
PLZ HELP.
[...] with 3.71 M33, 3.71 M33-2 or 3.71 M33-3 custom firmware. For newbies, you can see the version of your PSP on your [...]
After upgrading to any of the M33 can i format my mem stick?
@Dan: anytime you like
When first I didn’t know that you had to put the game folder on 3.52 kernel, the psp would just shut off, so I was like… dammit.
Then I flicked off the computer and got freaked out by the official PSP 3.71 update.
LOL.
Thank you very much for your excelent work!
It worked real fine!
Tank you! Sir!
bricked it.
i installed the update from m33 3.52-4, claimed it needed to fix something from a previous downgrade, fixed it, freaked out about legit installer, cancelled, checked firmware to make sure it was right, tried installing again, told me i needed 78% battery, tried left and triangle override, did nothing. turned it off. tried to turn it on again, now nothing. green light, no screen. plz help.
thats called a brick
thank you so much! This guide is a great help saved me a lot! PS. this guide is much clearer and easier to understand than any guide found on the net so far. THANKS!!!!
hey ex-pizzaboy

if you did your in luck as i can supply all software needed to unbrick and easy install up to 3.52 m33-2-3-4
ron
does ur pp have to be in 3.52 mode in revoery to do this and also do you have to format your memory stick before you put the update floder in it
Yeah sorry about my last post but i just upgraded to 3.71m33 and it was working fine then it came up with a data corrupeted message in japanese but everything is working fine thoe
I have put M33 3.71 on my PSP but it saying no update required. My PSP is a 3.80.
Any Ideas?
When I try to run the update from my PSP, it verifies the 3.71 first, and then in the next line it says something like “error idsgeneration” and then restarts.
What gives?
hello…
ı foollowe dyour guide and now my psp is 3.52 m33.4.. for the next step ı had tried to upgrade it to 3.71… when ı starded the upgrade program ıt says…
“some of your idstorage keys have not the correct values, probably due to a downgrader. In order to continue, press X to restore the correct values, press R to exit.”
ı press R and exit… ı read the forum and see two problems having this error… one was succesful by pressing x the other bricked psp… what is the reason of that error… what should ı do…
@dshelpplz: If you really wanna go to 3.71 M33 then you should press X to fix your ID storage keys. But that’s up to you. I have seen that too many times when I’m installing custom firmwares and I must say I’m 100% successful. But really, it’s your choice dude. Do it at your own risk.
actually if ı knew what are the idstorages ı will feel safe and continue the installition. if it has an importance my board is ta082…

@toma: Don’t update from the Network update in your PSP. It won’t get bricked but you won’t be able execute homebrews.
am running version 3.71 on my new psp lite. trying to update so i can use dark alex’s firmware and increase the brightness etc because my eyesight isnt that great. also, a couple of the games i downloaded from the ps store dont run and i get an error msg. any help appreciated. thank you very much.
Then turn on your PSP again while holding your R button down. This will take you to the M33 recovery menu.
That’s Very Difficult.
@Andre Blight:
You have to shut down, not put it in sleep mode, to do this, hold the power b,utton up.
how to install the 3.71 m33-4 version to my psp the version of my psp now is 3.52 m33-4
I get a message saying that i requires 3.52 m33-3.
I have 3.52 m33-4 installed, so i don’t know why I m getting this message.
@james: You need to set your Kernel to 3.52.

Hi
Everything seemed to be going well, followed the guide to upgrade from 3.30 oe-a to 3.52 m33 then to 3.52 m33-4 so i thought we would go to 3.71 m33, reort said some files not correct and press x to correct it so i pressed x it said successful then i got a error DRNFFFFFFB0 or O, now i have just a power light and a black screen.
PLEASE HELP
Thanks
Raymond
@Raymond Edwards: Your PSP may be semi-bricked. Try to access the recovery menu – Turn your PSP off, slide the power button up for 15 secs. When the green light is off wait for 5 secs and then Press the R button and while pressing it, turn on your PSP. You’ll be taken to the recovery menu. From there you can install a 1.50 firmware into your PSP.
the epitome of a perfect tut
installed 3.5 and 3.7 with no problems. keep up the great work!
when we do it do we put the update into game or game150, cuz arent we supposed to use the game150 instead if game?
@Victor Cunas
Read the directions, everything’s already there.
i get the same error!!
i got it, restart pressing R then select the kernel folder to 3.52 instead of 1.50 and then run the updater
good luck
sorry it was the other way (the posts) i was repling to the botom one

I had the same problem that it says that it should have higher version ..and I figured why….just follow these steps :
(Shutdown your PSP. Then power on your PSP while holding down your R button. This will take you to the recovery menu. Go to Configuration > Game folder homebrew and check if 3.52 is enabled. Press X or circle if not. Exit the recovery menu.)
this is based on the instructions above and it worked …
how did i get the m33 for my psp 3001 v5.03? or how can downgrade my psp 2001?
you are the best, my psp can update properly now
Hello there.
I’ve been recently having problems with my PSP lately. This hasn’t happened before.
I have two games in my PSP right now, with 94 MB to spare out of 4 GB memory. That would be Dissidia Final Fantasy, 1.64-ish GB and Smackdown vs Raw 2009 which is also around 1.00+ GB. I haven’t updated my firmware ever. I’m using the fat PSP. My firmware is around the 3.00 version.
Whenever my brother and I play the games, sure, they work, but at certain parts of the game, it freezes, and shuts down.
May I ask what should I do? Please help me >: Thank you very much.
my psp version is 3.52 m33-4 and i wana play game ben 10 alien force and it says update to version 4.05. how i do this
